- WINDOW Loc'x Application filed December 31, 1930.` Serial lNo.7505,7'31; K *i ,I

This invention relates to improvements in devices Jfor locking sliding window sashes 1n their relative positions leaving the window` partly 'open for yVentilating andv otherpury 'device 'seen'in the Vdirection ofarrows 55 5 poses, and it is the principal object of my in'y vention to provide a locking bar in form of a hook adapted to engage a keeper on one of the sashes andl havingV `a lowershank adapted to be guidedin a sleeve having its l() front partly slotted toallow the removal of the bar with the Window closed and equipped with means to lock the bar in its sleeve engaging position, with the Lwindow partly o en. f

l?? .pAnother object of my inventionis thepro- .vision of a window lock of simple andthere- Vfore inexpensive construction, yet durable and highly eiiicient in its operation, which can be readily attached to and removed froml 3* any `window without the necessity of materi-` 1 y `ally changing the lwindow construction'.

VA further object of my invention is the provision of a window lock vincluding a keep# er having'an opening and a locking bar en 3? gaging the same and provided with a notch near one of its ends adapted to be engaged by the Wall of the keeper Aforming its openincr.

tstill further object of my invention "i" the provision of a locking bar for window locks having a toothed part formed With its shank adapted to be engaged by 'a screw bolt passed through a guide sleeve for saidbolt forV locking the locking bar in' any of its ver- "V tically adjusted. positions. f

AThese andfother objects and advantages of my invention will become more fully'apf parent as the `description'thereof proceeds andwill then be more specifically defined in Wl theappnded Claims' n In the accompanyingdrawings forming a material part'of this disclosure: Fig. 1 is a fragmentary perspective View Y of a window equipped with a lock constructed f '5 according to my invention. f' l Figa@ is a sectional side elevationthereof, With the windows closed. Fig. 3 is azview similarfto lFigure 2 with P the window partly open. y v f "L1 Fig. 4 is a fragmentary side elevation of ay thelendof itsupper angularly benthook part pair of window sashes equippedl witha locking ydevice constructed according" to my inL vention on an enlarged `scale*V f Fig. 5 ispa front elevation of the lockingk 55 infFigure 4. f

@As illustrated,the upper sasli 150 of ajwindow -11,and the' lower sash 12er a window `1 3 are arranged "for jthefusual sliding ver-1vr 'tical reciproca'torydisplacement in the Win#v 60 dow framesl 14- and fl5respective1y l TheA locking device :according tol my in-,rv ventioncomprises akeeper 16 adapted to be secured tothe innerface ofthe upper lsash at, a.V certain distance `fr'omits flower end and,v havinga central opening formed therein.

A; hookshaped member 17 v'is adapted' to'Y engage the central opening'of the keeper-withk I while thelower straight shank oit the-hook member engagesiendwisea sleeve or socket 18-attached ltothefsas'h of the lower'fwindo'w -1 at a'f'ce-rtainjdista-nce from'its upperiend.'

@The vhook parthasa notch 16formed in itsfendto be engaged by he wall forming the perforation insaid keeper.: The sleeve 18fislongitudinallyfslotted at its front,l as'v at l 19 for a distance while its?y lower end is closed. In the `closed part eni gagesascrewfbolt 2O having at its outer end a thumb `piece 21`while its innerv end lis adapted to engage the intervals betweentwo f teethof a toothed portion 22y at the front of theshank of hook 17. Theoperation of my devicewillbe entirely clear from the above description and by simultaneous inspection of the drawings and it will be evidentthatthe-'windowsl can be opened kto aYcertain degree and the^`s'ashes be lockedintheirrelative position bythe engagement of the hook 17 with its keeper the walls ofthe keeper opening engaging the notch 16 ofthe hook member, and the proper adjustment ofthe hook shank and locking of the same by means'of the engagement of the screw bolt `20 betweenthe teeth 22' of the toothed part of the `hook while lthe screw is f f tightened byv means of the proper operation ofthe thumb piece 21. The longitudinal slot 19 in .the sleeve allows a disengagement of` the hook shank therefrom as indicated in broken lines in Figure 2 is the Window is entirely closed.

It will beclear that in this manner the upperl as well as the lower sash of a window may bey operated to a desired degree and will then he locked in their relative adjusted positions making it impossible for an outsider to enter a room or to tamper with the window lock.

It will be understood that I have described and shown the preferred form of my device only as one example of the many possible ways to construct the same, and that I may make such changes in the construction of the device as come Within the scope of the ap pended claims without departure from the spirit of my invention.

Having thus described my invention what i Y.

I claim as new and desirek to secure by Letters Patent is:

l. A lock for sliding window sashes comprising akeeper having a central perforation secured to one of the sashes', a hook member engaging the perforation in said keeper, a Vsleeve secured 'to the other sash and having its front partially slotted, a shank on said hook member for-endwise engage-v Yment in said sleeve, a toothed part on said hook member, a screw bolt inthe non-slotted part of said sleeve adapted to engage said v toothed part, and a thumb piece for operating said screw bolt to lock said sleeve and hook member in their relative adjusted `position with the window partially open.

2.- A lock for sliding window sashes comprising a keeper. having a central opening and adapted to be secured to one of the window sashes, a member having a hook formed at its upper end notched to be engaged by the walls forming the opening in the keeper member upon engagement of said hook in the opening of said keeper, a sleeve secured to the other window sash, partially slotted at its front, a shank formed with saidmember for end-wise engagement in said sleeve, and

adapted to be disengaged from said sleeve through the slot therein with `the Windows closed, and means for locking said shank in said sleeve with the sashes in their window opening position. l
